Cli.Fyi – A CLI Tool To Fetch Information About IPs, Emails, Domains And Lots More

By sk

A while ago, we discussed about Bash-Snippets, a collection of useful BASH scripts for heavy commandline users. Today, we will see a similar utility called "Cli.Fyi". It is a command line query tool to fetch information about IPs, Emails, Domains, Crypto currencies, media/url, UTC date/time, country and programming language etc. You can fetch all these details either from commandline or browser. Unlike Bash-Snippets, Cli.Fyi command line query tool is not a collection of individual scripts but a single utility. It has some additional features that are not included in Bash-snippets.

How To Use Cli.Fyi Command Line Query Tool

Usage is absolutely easy! Just use "curl cli.fyi" command in the Terminal followed by a query after a forward-slash (/).


$ curl cli.fyi/time

Replace "time" with your query in the above example.

Sample output for the above command would be:

 "type": "Date/Time Information (UTC)",
 "data": {
 "day": "07",
 "month": "11",
 "year": "2018",
 "hour": "06",
 "minutes": "11",
 "seconds": "11",
 "dayName": "Wednesday",
 "monthName": "November",
 "amOrPm": "am",
 "unixEpoch": 1541571071,
 "formattedDate": "Wed, 07 Nov 2018 06:11:11 +0000"

The currently supported queries are;

  • Crypto Currency prices,
  • Email Address details,
  • IP Address details,
  • Media/URL details,
  • Client details,
  • String Hash Values,
  • Domain Name details,
  • Date/Time details,
  • Programming Language links,
  • Country details,
  • Popular Emojis.

The author might add more utilities and/or features in future, so I recommend you to keep an eye on the project's website or GitHub page for future updates.

Let us see few examples.

Display price of a crypto currency
